An apparatus and method for reproducing multimedia contents regardless of the type and version of a codec, an apparatus and method for generating multimedia contents, and a storage medium storing multimedia contents are provided. The multimedia reproducing apparatus includes: a reading unit which reads multimedia data including multimedia contents coupled with a codec for decoding the multimedia contents, from a storage medium; and a reproducing unit which reproduces multimedia contents by using the codec extracted from the read multimedia data. Regardless of codec upgrade or introduction of a new codec with a new method, various types of multimedia contents can be smoothly reproduced.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A multimedia reproducing apparatus comprising: a reading unit which reads multimedia data comprising multimedia contents coupled with a codec for decoding the multimedia contents, from a storage medium; and a reproducing unit which reproduces the multimedia contents by extracting and using the codec from the read multimedia data, wherein the multimedia data further comprises a header in which information on characteristics of the codec is recorded, and the reproducing unit comprises a general-purpose engine which executes the codec with reference to the header regardless of a type of a platform or operating system, and wherein the general-purpose engine decodes the multimedia contents by loading the codec in the storage medium into memory by referring to the header included in the read multimedia data and executing the codec.
2. The multimedia reproducing apparatus of claim 1 , wherein the storage medium includes at least one of an optical disc, local storage, and remotely located storage.
3. The multimedia reproducing apparatus of claim 1 , wherein the codec is implemented by a binary code or a script language describing the operation of the codec.
4. The multimedia reproducing apparatus of claim 3 , wherein the script language includes Java language, and the general-purpose engine is a Java virtual machine executing the codec implemented by Java regardless of the type of a platform or operating system.
5. The multimedia reproducing apparatus of claim 1 , wherein the multimedia reproducing apparatus is any one of a DVD player, a PC, a notebook computer, a personal digital assistant (PDA), and a consumer electronics (CE) product.
6. The multimedia reproducing apparatus of claim 1 , wherein the header is coupled with the codec and the multimedia contents.
7. The multimedia reproducing apparatus of claim 1 , wherein the multimedia contents includes the codec for decoding the multimedia contents.
8. A multimedia reproducing method comprising: reading multimedia data comprising multimedia contents coupled with a codec for decoding the multimedia contents, from a storage medium; and reproducing the multimedia contents by using the codec extracted from the read multimedia data, wherein the multimedia data further comprises a header in which information on characteristics of the codec is recorded, and wherein the reproducing the multimedia contents comprise reproducing the multimedia contents by using a general-purpose engine which executes the codec with reference to the header regardless of a type of a platform or operating system, and wherein the general-purpose engine decodes the multimedia contents by loading the codec in the storage medium into memory by referring to the header included in the read multimedia data and executing the codec.
9. The multimedia reproducing method of claim 8 , wherein the storage medium includes at least one of an optical disc, local storage, and remotely located storage.
10. The multimedia reproducing method of claim 8 , wherein the codec is implemented by a binary code or a script language describing the operation of the codec.
11. The multimedia reproducing method of claim 10 , wherein the script language includes Java language, and in reproducing the multimedia contents, the codec implemented by Java regardless of the type of a platform or operating system is executed.
12. The multimedia reproducing method of claim 8 , wherein the multimedia data is reproduced by any one of a DVD player, a PC, a notebook computer, a PDA, and a CE product.
13. A multimedia generating apparatus comprising: a contents generation unit which encodes multimedia contents by using a codec; and a recording unit which records multimedia data comprising the multimedia contents coupled with the codec, in a storage medium, wherein the multimedia data further comprises a header in which information on characteristics of the codec is recorded, wherein the multimedia contents is reproduced by a general-purpose engine which executes the codec with reference to the header regardless of the type of a platform or operating system, and wherein the general-purpose engine decodes the multimedia contents by loading the codec in the storage medium into memory by referring to the header and executing the codec.
14. The multimedia generating apparatus of claim 13 , wherein the storage medium includes at least one of an optical disc, local storage, and remotely located storage.
15. The multimedia generating apparatus of claim 13 , wherein the codec is implemented by a binary code or a script language describing the operation of the codec.
16. The multimedia generating apparatus of claim 15 , wherein the script language includes Java language, and the contents generation unit executes the codec implemented by Java regardless of the type of a platform or operating system.
17. A multimedia generating method comprising: encoding multimedia contents by using a codec; and recording multimedia data comprising the multimedia contents coupled with the codec in a storage medium, wherein the multimedia data further comprises a header in which information on characteristics of the codec is recorded, and wherein the multimedia contents is reproduced by a general-purpose engine which executes the codec with reference to the header regardless of the type of a platform or operating system, and wherein the general-purpose engine decodes the multimedia contents by loading the codec in the storage medium into memory by referring to the header and executing the codec.
18. A non-transitory computer-readable multimedia storage medium comprising: multimedia data including multimedia contents coupled with a codec; and information on characteristics of the codec, as a header, wherein the multimedia contents are reproduced by a general-purpose engine which executes the codec with reference to the header regardless of a type of a platform or operating system, and wherein the general-purpose engine decodes the multimedia contents by loading the codec in the storage medium into memory by referring to the header and executing the codec.
